Turn signal operation.

That does NOT work on my 2018 M3. It was the first thing I tried (and countless times after).

If it never worked, that suggests a hardware problem.
If it worked until the last software update, maybe reinstalling that update would fix the microcontroller for the stalks.

Half press in either direction should cancel either direction signal. If that doesn’t work then it’s broken. Note that full press will not cancel it. Only half press.

Are you sure it worked on 2018 models? It never worked to push to the side blinking to cancel regardless of if light or hard press.

I am wondering if they changed this on later models. I have a hard time buying its broken--and for both directions.

Good question. Another 2018 owner could answer, or ask via a service ticket.

The first owner's manual I downloaded was 2020.4:

There's no mention the 3-blink feature! Does that feature still work? Stalks only?

The 3-blink feature stopped working for me a while ago. A half press gives one blink.

Weird. In a test, turning off Auto Cancel restored the 3 blink feature. Then I re-enabled Auto Cancel, so half press again starts blinking until it cancels or I do.

This is in the description:

Tesla's 'Auto Cancel' Turn Signals and How They Work​

Tesla's 'Auto Cancel' Turn Signals and How They Work

Tesla's auto cancel turn signals is now available on all models. Here's how to enable and disable them, and how they work.

www.notateslaapp.com

When Tesla's Auto Cancel feature is enabled, the distinction between the soft press and click practically disappears. [...] This is a much more functional (and safer) way to drive since the blinker will only turn off once the turn is completed.​

​

For me, that second sentence is untrue. Auto cancel was always turning off the signal when I was in the turn lane which IMO is unsafe.

I think if you hold it too long in the half press position it will stop blinking as soon as you release. Try not keeping it there too long to see if it helps.

No need. I just RTFM on the screen. It says I can cancel the turn signal by the same direction. But it could have made it a little clearer. But I just now figured it all out.

Here is what I just discovered and never knew before:

Light push up or down for 3 blinks that MUST self-cancel out. No way to cancel. This must timeout. Mainly only good for a lane change.

Hard push up or for a turn signal that will only self-cancel in a turn OR very lightly push up or down in the same direction to cancel. If using the same force as selecting, it will NOT then cancel.

IMO, it would have been better if it required the same force to cancel as to select.

Well, now I have the entire thing figured out, but it is way too critical in the light force required to cancel the full turn signal. I will have to get used to that. But at least now I know how it is done.
